- CLAPMT rearranges the columns of the M by N matrix X as specified by the
- permutation K(1),K(2),...,K(N) of the integers 1,...,N. If FORWRD =
- .TRUE., forward permutation:
-
- X(*,K(J)) is moved X(*,J) for J = 1,2,...,N.
-
- If FORWRD = .FALSE., backward permutation:
-
- X(*,J) is moved to X(*,K(J)) for J = 1,2,...,N.

-
- M (input) INTEGER
- The number of rows of the matrix X. M >= 0.
-
- N (input) INTEGER
- The number of columns of the matrix X. N >= 0.
-
- X (input/output) COMPLEX array, dimension (LDX,N)
- On entry, the M by N matrix X. On exit, X contains the permuted
- matrix X.
-
- LDX (input) INTEGER
- The leading dimension of the array X, LDX >= MAX(1,M).
-
- K (input) INTEGER array, dimension (N)
- On entry, K contains the permutation vector.
